    The compiler did not find the kernel header file asm/system.h when I used Knoppix 7.0.3 CD.

    Greetings, Klaus2008.

    Klaus K suspects your rfkill idea may be the key to John's problem.
    I've also found two new references that seem to say John's wifi should
    work with b43.

    On the wl front, I've found several other distros also find problems compiling wl
    for kernels 3.4 and 3.5. Also two work-arounds. If you are interested
    you might look at these. I've found no Debian solutions yet.

    I think patching is beyond my level, so I'm not going that way.

    Re your post #7 utu:
    "So, you might decide to try building your own wl; or switch to 6.7.1;
    or we can continue to diagnose your 7.0.2 to see if it'll work with b43."

    Hi utu

    (Thanks also to you klaus2008 for your help).

    (A) I would have preferred to just find out which of the 5 Synaptic packages to
    install (broadcom-sta-source, etc) that I mentioned in my 1st post, but I've
    had a think, and, to stop sparks coming out of my brain, I thought it perhaps
    makes sense to just follow your kind step-by-step directions utu, and hopefully
    quickly get my wifi working.

    (In the meantime, sincere thanks to all others who are offering me help as
    well.)

    (B) Re your post #7 utu:
    "So, you might decide to try building your own wl; or switch to 6.7.1;
    or we can continue to diagnose your 7.0.2 to see if it'll work with b43."

    ... I'll go for the latter: "... continue to diagnose your 7.0.2 to see if it'll
    work with b43."

    Even if my wifi doesn't work with b43, at least you'll know what my system
    looks like, and hopefully will be in a better position to guide me through
    installing the Broadcom-sta driver.

    (C) So next I'll fill you in on what you asked for as per:
    "If the latter, do Klaus2008's test (see post #4)
    to make sure your wifi isn't disabled, then
    1. look in Synaptic and see if b43-fwcutter is installed; then, if it is,
    2. do modprobe --first-time -v b43, and lsmod | grep b43 again.
    Get back to us with your progress anyway."

    0. My results for klaus2008's test:

    knoppix@Microknoppix:~$ rfkill list all

    repeated it:]

    (D) By the way, thanks for the gracious way you pointed out that Werner was
    having to reformat my postings. I had no idea that my text was coming through
    strangely. All I've been doing is copying my text from the Kate text editor and
    pasting it into the posting text area. I'll follow your instructions about
    checking the formatting.

    (E) In actually IMPLEMENTING things on my system, I'd rather go the GUI
    approach (eg using Synaptic Package Manager) if that's physically possible. But
    if the only way is to type commands, I wonder if you could put a one-line
    description of what each command is doing, so that I actually KNOW what I'm
    doing.

    Don't worry if that's asking too much. I'm just very grateful for your expert
    direction.

    Bye for now. John.

    Outstanding, John.
    Thanks for confirming b43 gets installed. Klaus K will be happy.
    rfkill doesn't seem to be a problem. Often it is.
    You've done all the hard work.

    We'll have to mull over what else could be wrong.

    Need to understand the insmods. Did you do the insmods
    of was that a result of modprobe as root?

    How are you communicating with us, anyway?

    What do you get for ifconfig & iwconfig when using 702?

    Re: Which Broadcom STA driver do I install from the ones listed in Synaptic?

    Hi utu

    Thanks for the complement. I can cancel my subsription to plonkers anonymous
    now. Let me know when any of my colloquialisms sound like double-dutch to you.

    Does "modprobe --first-time -v b43" add the "b43" module to the kernel
    (as if I know what I'm talking about). Is this the SAME thing as INSTALLING the
    b43 driver? Is the b43 module a driver or is it firmware?

    After doing the above modprobe, I rebooted to see if the wifi was working but
    the orange wifi LED still doesn't come on, even when I toggle Fn + F3.

    The answers to your 3 questions:
    1. Communication: I've got an ethernet cable running between my laptop and my
    router. Router is connected to phone socket on skirting board, which goes to the
    outside telegraph pole of course. I think we were much better off with two tin
    cans and a piece of string don't you.

    I'm glad that YOU know what these outputs mean because i haven't the faintest.
    I've started using lower case "i" for "I" - a sure sign that I've been
    assimilated .

    Would you be good enough to tell me something? To get wifi working, is it
    normally just a matter of installing the correct wifi device driver in Linux,
    and then should the wifi work from that point onwards (you know - press Fn +
    F3 (in my case) and the wifi LED comes on)? (I realise that after that you have
    to select appropriate wireless settings in network manager to communicate with
    the router.)

    In Linux, what are the actual STEPS in setting up the wifi. I WOULD like to
    know. At the moment I haven't even got a mental picture of what goes off -
    just a confused mush. In Windows for example, I presume that what one would do
    is, in Control Panel, select the correct wifi driver for the wifi circuit-board
    in your PC. Then any software that communicated via the wifi would communicate
    with the wifi circuit-board via the wifi driver.

    Ta ta for now. John.

    Greetings again, John

    If b43 is installed already and you command 'modprobe b43',
    you get no response, and no information.

    If b43 is installed already and you command 'lsmod|grep b43',
    you should get the response
    b43 298744 0
    bcma 16433 1 b43
    ssb 35297 1 b43
    rng_core 2363 1 b43
    pcmcia 25367 2 b43,ssb
    mac80211 283250 2 b43
    cfg80211 116931 3 b43,mac80211

    If b43 is installed already and you command 'modprobe --first-time -v b43',
    you get the response "ERROR: could not insert 'b43': Module already in kernel"

    If b43 is available and NOT already installed and you command 'modprobe --first-time -v b43'
    THEN, I think you get all the insmods, as you did, bringing in all the modules listed above.
    knoppix@Microknoppix:~$ sudo modprobe --first-time -v b43
    insmod /lib/modules/3.3.7/kernel/drivers/pcmcia/pcmcia.ko
    insmod /lib/modules/3.3.7/kernel/drivers/char/hw_random/rng-core.ko
    insmod /lib/modules/3.3.7/kernel/drivers/ssb/ssb.ko
    insmod /lib/modules/3.3.7/kernel/net/wireless/cfg80211.ko
    insmod /lib/modules/3.3.7/kernel/net/mac80211/mac80211.ko
    insmod /lib/modules/3.3.7/kernel/drivers/bcma/bcma.ko
    insmod /lib/modules/3.3.7/kernel/drivers/net/wireless/b43/b43.ko

    It looks like you have b43 available but it is not being AUTOMATICALLY installed.
    Since we know b43 is available, you can do a modprobe b43 to install the drivers YOURSELF
    and see then if the wifi is recognized by network manager, the icon on lxpanel.
    A left-click on this icon shows your choices for ethernet and wifi'
    a right-click show your choices to enable/disable these choices.

    If you have a wifi CHOICE and it's enabled, a right-click should either
    connect you to this choice or present you with (at least) a query about WEP
    or WAP parameters. Other parameters may also be needed.
    The same choices that worked for a Windows handshake work here.

    In my case, my wifi choice is a Verizon router which answers on 192.168.1.1 which
    automatically assigns me a local 192.168.1.x address and does DNS look-up
    service for the internet. All I have to know is its assign NAME and mac address.
    The NAME shows up in the CHOICE previously mentioned.

    Your router, WEP/WAP and DNS situation may be different than mine.

    I'm hoping you just need to struggle your way through this hand-shaking process.
    We need your confirmation that b43 works for you, so hang in there.

  7. #17

    Stop Press utu

    I had just started reading your #16, then for my own information, i tried

    knoppix@Microknoppix:~$ modprobe --dry-run -v b43
    insmod /lib/modules/3.3.7/kernel/drivers/pcmcia/pcmcia.ko
    insmod /lib/modules/3.3.7/kernel/drivers/char/hw_random/rng-core.ko
    insmod /lib/modules/3.3.7/kernel/drivers/ssb/ssb.ko
    insmod /lib/modules/3.3.7/kernel/net/wireless/cfg80211.ko
    insmod /lib/modules/3.3.7/kernel/net/mac80211/mac80211.ko
    insmod /lib/modules/3.3.7/kernel/drivers/bcma/bcma.ko
    insmod /lib/modules/3.3.7/kernel/drivers/net/wireless/b43/b43.ko
    knoppix@Microknoppix:~$
    knoppix@Microknoppix:~$ lsmod|grep b43
    knoppix@Microknoppix:~$

    I used "--dry-run" because I believe it's just a simulation and doesn't actually do anything. I thought this would be a safer way of just trying it again.

    BUT BUT BUT
    i thought that the other day we established that i had just ADDED b43 to the kernel (post #13). But the above code now indicates to me that b43 IS NO LONGER IN THE KERNEL.

    So I wonder if the Linux system is REMOVING b43 at each bootup (if it's in the kernel).

    Here's the current blacklist-knoppix.conf if it's useful:

    # modprobe blacklist for KNOPPIX

    # HP Mini 110 PC wifi w/wl.ko breaks if ssb is loaded,
    # but b43* requires ssb
    # blacklist ssb

    # if b43* are used, wl.ko should NOT be auto-loaded
    blacklist wl

    # graphics/KMS drivers should not get autoloaded by udev
    blacklist nvidia
    blacklist nouveau
    blacklist nvidiafb
    blacklist intelfb
    blacklist mbp_nvidia_bl.ko
    blacklist rivafb
    blacklist i915
    blacklist radeon

    Hope this is useful information.

    Simplified Post #16

    1. simply boot up
    2. do, as root, modprobe b43
    3. check lsmod|grep b43
    4. If you get b43 and all its dependent elements as you once did,
    start on all the hand-shake stuff I gave you.

    Greetings again, John.

    I see your situation as having several hurdles to get over

    0. Is our assumption correct that b43 should work with your wifi?
    1. Does your Knoppix 7 install have its basic integrity or is it broken somewhere?
    2. Were b43 and its supporting driver modules provided to the kernel by Knoppix?
    3. Is your wifi hardware in working condition?
    4. Have you provided workable hand-shake parameters to Network Manager?
    5. Is your router or other network connection in working order;

    0a. Is what Klaus K and I would like to know for sure.
    0b. We are aware the wl driver works for your wifi; we weren't aware Knoppix 7 would not
    provide wl as a backup alternative. There was a new kernel conflict we hadn't expected.
    1. I'm not sure. I'd like to see what you get for testDVD on your DVD.
    2a. I think we established that they are available, but may not be automatically installed.
    2b. We can probably fix the automation rather easily.
    3. You can verify or have verified this with your Windows set-up.
    4a. Same as answer 3, simply use identically the same parameters as for Windows.
    4b. An excursion to some new set of 'Post Office' parameters is not recommended.
    5. Same as answer 3.

    If things aren't working just yet, then there are things for you to do in 1, 3, 4 and 5.
    I'll help you improve on 2 after you tackle the others successfully.

    If you get stuck somewhere, tell us where you need help.

    Re your question at #14 that I missed.

    Hi utu

    Re your question at #14:

    "Need to understand the insmods. Did you do the insmods
    of was that a result of modprobe as root?"

    Sorry I missed it. The answer is: No, I didn't do the insmods. What you see there, was the actual output from the "sudo modprobe --first-time -v b43"
    (ie "insmod /lib/modules/3.3.7/kernel/drivers/pcmcia/pcmcia.ko " etc).
